摘要: 为了保证抽油机的长冲程、低冲次的运动特性,提高换向系统寿命和可靠性,降低运转噪音,研制了一种新型滚筒式抽油机。针对该抽油机进行模拟加载试验,试验在理想化有杆泵采油的条件下实时采集悬点载荷与位移信号,并将采集的试验数据进行曲线拟合处理得到泵示功图,通过分析抽油机泵示功图,分别给定抽油杆配重负载和电机频率,研究了不同条件下抽油机运动规律的光滑性和无冲击性,使得抽油机泵示功图曲线趋于平缓,以此来获取抽油机最佳匹配的平衡配重和冲次,达到抽油运转稳定和节约能耗的目的。通过试验验证了该方法的准确性以及抽油机传动换向系统和平衡系统的可靠性,为抽油机模拟加载特性研究的型式试验提供了新思路,具有一定的参考价值。

Abstract: In order to ensure the long stroke and low stroke motion characteristics of the pumping unit, improve the life and reliability of the commutation system, and to reduce operation noise, a new type of drum pumping unit is developed and a simulation loading test is performed. The test collects real time load and displacement signals in the ideal condition of rod pump oil extraction, and performs curve fitting processing on the collected experimental data to obtain the pump indicator diagram. Through analysis of pump power diagram, we make a study of the features of smoothness and impactlessness features of pump movement under different conditions by giving sucker rod weight load and motion frequency, and got a flattening pump power diagram. In this way, the optimal matching balance weight and stroke of the pumping unit are obtained, achieving stable pumping operation and energy saving. The accuracy of the method and the reliability of the pumping unit\begin{document}$ ' $\end{document}s drive reversing system and balance system are verified through the experiments, which provides new ideas of the type test of the simulated loading characteristics of the pumping unit, and has certain reference values.

Key words: drum pumping unit, pump power diagram, load simulation, frequency, balance weight
